Digital vs formal teaching of vaginal breech delivery: Which is the residents' choice?

A critical area of obstetrics that demands proficient training is the management of breech deliveries. There was a notable decline in the number of vaginal breech deliveries in the following years, establishing CS as the preferred method of delivery for such cases. Cohort studies using targeted screening and skilled practitioners demonstrated little differences between the two delivery. Skills acquisition at the patient's bedside is very difficult to obtain, particularly in the youngest trainees. Simulation teaching has largely become a part of the training curricula for many obstetrics and gynecology residency programs.

This was a prospective, randomized, controlled, single-center study. Residents were randomly assigned in two groups with similar characteristics. Group A attended a formal lecture. Group B received the study material and recording of the lecture as digital home learning. Lecture and simulation focused on vaginal breech delivery. After one month both groups underwent a simulation test addressed to assist a vaginal breech birth. Four supervisors evaluated all videos. Time needed for birth, and evaluation scales as Objective Structured Clinical Examination were recorded. A questionnaire was completed online using Google Forms with 6 questions. The primary outcome was to compare the evaluation for each item and globally within groups. A secondary outcome was the evaluation of questionnaire results within the two groups.

Thirty-two participants were recruited and randomized. None of the participants withdrew from the study. For the primary outcome, all examined variables (Time, Rumping, Legs, Body, Arms, Head, Total Point) did not present differences in supervisors' evaluations. For the secondary outcome, Group B showed higher values in two questions.

The major finding of our study is that digital learning and formal lecture presented similar results on resident knowledge. Teaching programs involving mannequin simulation - both high and low fidelity - are reproducible and efficient for skill retain in obstetric emergencies, particularly in low incidence emergencies. The main limitation of our study was the small sample size. In addition, it is possible that a scenario without deviation or a lecture more focused on possible deviation from normal could modify residents' results facing breech delivery.
